Brickworld 2007, June 21-24, Chicago

Indy 5.00:

Autonomous robots will run head-to-head races of five laps around a 8’x10’ oval
gradient track. The event will be double-elimination or round-robin style
(depending on the number of participants; single elimination is a possibility).
The winner of each race will be the robot that cross the finish line first.

Arena:

The oval track will have a smooth black and white gradient across the surface
(darkest black at the “inside lane”, fading smoothly to lightest white at the
“outside lane”; see for example
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=288812), so that by trying to
remain in a certain gray “zone” on the track the vehicle will remain in a
certain “lane” on the track (note: the gradient will be as smooth as possible,
not actually a series of separate “lanes” or “tracks”). The oval will be
centered on a 4’ by 8’ surface, with no rails or other physical limits. However
the outside of the track as well as the inside will be marked with a string or
light rod balanced on stands, so that if a robot hits either of these limits it
can be detected and time penalties can be assessed. The track will be made
available for pre-race testing and tuning the day before, so that everyone can
have a chance to adjust to the track and lighting in question. The starting line
will be defined by a mark outside the oval itself (so that nothing interferes
with the smooth gradient) roughly halfway along one straightaway, and all races
will take place in a counter-clockwise direction.

Event structure:

Before the actual race each robot will be allowed one minute or five laps (which
ever comes first) to establish the robots qualifying time: the shortest single
lap during this “speed trial” will be that robots qualifying time. Each
individual race will be a match between two robots, with the one with the lower
qualifying time getting to selecting starting position first. Once both robots
have been placed, the judge will ask the competitors to start their robots
simultaneously. If at any time during the race a robot either is unable to
continue (crashes, stops, breaks) or crosses the inner or outer boundary, that
robot will be stopped and removed from the track. If the other robot is not
likewise incapacitated, it will be allowed to finish the lap it is on. Once it
has crossed the line, both robots will be restarted on the line with each robot
being credited only those laps which it has completed a complete circuit of the
oval. The first robot to complete 5 cumulative laps will be declared the race
winner.

Robot design and limitations:

All robots must be constructed of 100% unmodified LEGO parts (that is, any part
that can be bought directly from LEGO, be it Shop-at-home, LEGO Education,
etc.): no gluing, cutting, melting, or other modification or modified pieces are
allowed. Robot size must be no larger than 6” by 10”, running long ways down the
track. The robot may not at any time exceed this 6” by 10” footprint, but there
is no weight limit. All robots must have a standard placement front and rear
bumpers: This is defined as the height of a Technic beam connected to the axle
of  a LEGO Mag wheel (49.6x28 VR), as included in the RIS kits (see
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=691461 for an example – the
bumper should be at the height of the red Technic beam in this figure). Note
that it is not required that the robot use these wheels, only that the bumper is
set at this height. The bumper must be straight and not angled or sloped (i.e.,
it must be perpendicular to the direction of motion), and must extend across the
entire width of the vehicle. The goal is to keep competitors from becoming
entangled or locked together during a race. Robots must be completely
autonomous, and come with a 3 second built-in delay upon starting. There is no
need for the robot to recognize when it has completed the course, however.

Judges discretion:

All disputes about these rules and their interpretation will be adjucated by the
judges at the event (although requests for clarifications should be made as
needed, prior to the event). The judges discretion will be final, and will
attempt to enforce the spirit of the event.

(...) Okay, I'm confused. How can an 8' x 10' track be centered on a 4' by 8' surface? What is the actual width of the track? If the whole track fits on a 4' x 8' surface, then I would assume the width must be less then 2'. Gus (17 years ago, 17-Jun-07, to lugnet.events.brickworld, lugnet.robotics)

(1) "the bumper should be at the height of the red Technic beam in this figure" Does this mean that a the design must use a studded beam? (A stud-less beam is not as "tall" as the beam in the image.) (2) "The bumper must be straight and not angled (...) (17 years ago, 17-Jun-07, to lugnet.robotics)
